They are sized so much smaller than Underjams. My son just moved up into the underjams L/xl and they were bordering on too big but the s/m were too small. He is 55lbs. The new ninjamas fit him but he will not be able to wear them for long. I expected he could wear these for several years until he reached at least 100lbs, but with the current sizing, that will not happen. My son has cerebral palsy and wears these 24/7. I truly hope you will consider resizing them or adding an XXL option. My son is 44” tall and 55lbs, so in no way consider large or chubby and the L/XL fit perfectly. This means for larger children, they will fit too small. As for the technology, they are great! No leaks! Love the waistband! I am disappointed that the price increased a little and the count per box decreased by almost 1/4.

[This review was collected as part of a promotion.] My 4 year old son has struggled with potty training at night due to being afraid of the dark. We tried nightlights and even put him in a room with his own bathroom, nothing worked until we put these on him! We told him they were special ninja underwear that helped get you to the bathroom safely...and it worked first night! He thinks theyre the coolest.

[This review was collected as part of a promotion.] I recieved these Ninjamas for free for review purposes from Topbox circle. I love them! My daughter has been wearing them to bed to prevent leaks and accidents. They don't look like diapers so she feels more comfortable wearing them compared to the leading brand.

[This review was collected as part of a promotion.] My daughter received these samples to try on. At first she was not too sure because it's another brand than the usual we buy. As a mother of a special needs child, i have always wanted whats best and comfort is my priority for her. The "Ninjamas" are so cute and look really comfy. It's a must have for a great night sleep. Thank you for these samples and we will surely buy more!

[This review was collected as part of a promotion.] Received Ninjamas from Topbox in exchange of my honest review. I've seen it in stores so many times,but never tried the product until now. To start of the pull up colours are really cute and simple. My child wore it to bed and happily we did not have any leaks, good quality and the waistband helps keep the pull up diaper in place helping avoid any accidents. definitely at peace and glad to have found the Ninjamas. Also I did find the pull ups have a mild scent which helps protect against any odour

[This review was collected as part of a promotion.] My youngest son is 6 but still routinely fails to wake up when he needs to potty. These fit him comfortable, have cute designs and do a great job typically. However sometimes there are occasions when he manages to overflow them or they leak.

[This review was collected as part of a promotion.] I tried these out w my little boy who currently is potty trained but wears a pull up to bed. He loves them!! They feel super soft unlike the other brands we've tried out and they keep him dry all night. I'll def have to pick up more for him when these are gone.

[This review was collected as part of a promotion.] Love love love absolutely love. My son has been in pull ups and he never fails to leak at night. These have been a game changer. He even says they are comfy. Highly Recommend and weird side note. They smell like bubble gum or something to thag effect. Haha

[This review was collected as part of a promotion.] My son is 8 & occasionally still wets the bed at night. Hes a heavy sleeper - these nighttime underwear were wonderful for him. They have a nice scent so when/if he does pee, the smell isnt strong like with other pull ups. Definitely recommend!

[This review was collected as part of a promotion.] ok. off the bat.. they fit like a dream..I have a 4 year old who is very stout and still uses trying pants while sleeping..its next to impossible to find anything that fits his body. these are amazing. they are SUPER absorbent and come in really cute designs.will be 100% purchasing going forward!
